NOTE:
This bulletin applies to CS models with a 3.5 or 3.8L engine, (sales codes EGN & EGH respectively) and RS/RG models with a 3.3 or 3.8 engine, (sales codes EGA, EGM or EGH).
SYMPTOM/CONDITION:
The throttle plate and bore may become coated with contaminates from the intake system.
DIAGNOSIS:
If the throttle body plate and bore are coated with contaminates, perform the Repair Procedure.
PARTS REQUIRED:
REPAIR PROCEDURE:
1. Remove the throttle body from the engine; Refer to the detailed removal procedures available in DealerCONNECT > Service > Repair > TechCONNECT > 14 - FUEL SYSTEM > FUEL INJECTION > THROTTLE BODY > REMOVAL
2. Spray the entire throttle body bore and both sides of the throttle plate with Mopar Throttle Body Cleaner, p/n 04897156AA. This will remove the bulk of the contaminant.
CAUTION:
This cleaner should only be used in a well ventilated area. Do not allow contact with skin or eyes. Rubber or butyl gloves and safety glasses are recommended. Wash thoroughly after use. Do not ingest.
NOTE:
Use only Mopar Throttle Body Cleaner, the use of other cleaning agents may damage components of the throttle body.
3. While holding the throttle open, use a small, (1" x 1") piece of green Scotch Brite scuff pad, (or soft bristle brush), clean the throttle body bore and throttle plate, (including edges).
NOTE:
It is important that this cleaning procedure be performed thoroughly and completely. The edge of the throttle plate, and the portion of the throttle body bore where the throttle plate comes to rest are the most critical areas where the cleaning should be concentrated. These areas must be free of all deposits when the cleaning is completed.
4. Thoroughly clean the throttle body with Mopar Throttle Body Cleaner, p/n 04897156AA, and blow dry with compressed shop air. Inspect for any foreign material which may have been left from the cleaning process.
CAUTION:
Do not blow shop air pressure directly into the throttle shaft or throttle body housing holes.
5. Open and close the throttle on the throttle body to verify that there is no binding when moving off of the closed position. If the condition is corrected, proceed to the next step. If throttle still binds when moving off of the closed position, further diagnosis and/or repair will be necessary.
6. Clean all throttle body to intake manifold mounting surfaces thoroughly and install the throttle body on the engine; Refer to the detailed installation procedures available in DealerCONNECT > Service > Repair > TechCONNECT > 14 - FUEL SYSTEM > FUEL INJECTION > THROTTLE BODY > INSTALLATION.
